I just received Garrison's Damselfly Genera of the New World & and am anxiously awaiting Dragonfly Genera of the New World. These sure go where my Oregon & West Coast field guides don't. I see I'm going to have to keep the net handy because I rarely can get all the photos needed of any one specimen for a proper ID. My best guess for now, or correctly from an expert.
A bit different with dragonflies. You can see parts what you net them.
I have Paulson's Dragonflies and Damselflies of E. US. Just takes me forever.
Enjoy the day.
